Anatomy of the Femur Bone: The Pillar of Support for the Human Skeleton

Femur

Introducing the most Massive and Strongest (in most ways) Bone in the Human Body

There are 62 bones in the legs: 10 trunk/hip bones, 14 ankle bones, and 38 foot bones. The femur (thigh) is the largest and strongest of these bones. Most land mammals capable of jumping also have femur bones, also lizards, frogs, and other tetrapod vertebrates. Its length on average is 26.74% of a person’s height, a ratio found in both men and women and most ethnicities with only restricted variation.

A Few Femur Bone Stats

  1. the Femoral neck sits at a 125 degree angle
  2. Femurs can resist 1,800-2,500 pounds of stress
  3. Vehicular accidents are the primary cause of breakage

The Greater Trochantergreater_trochanter_grays

The Great Trochanter is a large, irregular, quadrilateral eminence on the upper portion of the femur bone. This portion of the bone has several, extremely important muscle insertions for the thigh and hip bones:

The lateral surface, quadrilateral in form, is broad, rough, convex, and marked by a diagonal impression, which extends from the postero-superior to the antero-inferior angle, and serves for the insertion of the tendon of the gluteus medius.

Above the impression is a triangular surface, sometimes rough for part of the human_ape_femurstendon of the same muscle, sometimes smooth for the interposition of a bursa between the tendon and the bone. Below and behind the diagonal impression is a smooth triangular surface, over which the tendon of the gluteus maximus lies, a bursa being interposed.

The medial surface, of much less extent than the lateral, presents at its base a deep depression, the trochanteric fossa (digital fossa), for the insertion of the tendon of the obturator externus, and above and in front of this an impression for the insertion of the obturator internus and superior and inferior gemellus muscles.

The Lesser Trochanter

The Lesser trochanter is on the underside of the femoral head and also has several muscular insertions: The Psoas Major on bottom and the Illiacus on top.

The Femoral HeadFemur_insertion_point

The Femoral Head is the highest part of the femur bone, support by the femoral neck. It inserts as a ball/socket joint into the Hip/Ilium via the structure depicted to the right.

The Femoral Neck

The Femoral neck usually sits at a 120-135 degree angle with some variation. A fracture of this area is known as a hip fracture and happens during aging. This structure supports the head of the femur bone and its insertion into the hip.

femur_pic_grays_2The Femoral Body

The Shaft of the femur is somewhat curved and has a protruding ridge called the linea aspera (rough line). The area of the bone supports the strongest muscle tissue in the body, including the hamstrings, Quadriceps, and thigh musculature. The Vastus Laterallis (outer quadricep) and adductor magnus (inner thigh muscle) connects into the linea aspera.

Lower Portion of the Femur

lower_femur_graysThe Lower portion of the femur bone consists of two condyle (from the Greek word for knuckle), lateral and medial that create the surface for the upper tibia bone and the knee-joint. Coated meniscus tissue layers on top of the bone and provides synovial fluid for frictionless movement within the knee. The medial (inside) condyle is the larger than the lateral due to its increased weight-bearing. 

How the Femur Bone affects your Holistic Health

Femur bone fractures correlate with increased disease in the elderly. It is safe to say that the femur bone is an organ that houses much of the mineral deposits for the body. Therefore, as we age and the bone tissue become more porous, this bone become one of the primary areas of decomposition.

One of the primary aspects of bone health is acquiring enough calcium to maintain bone density. Most calcium is available via leafy green vegetables, notably kale, bok-choy, and broccoli. Sodas and carbonated beverages make it harder for the body to absorb calcium and should be avoided by those with osteoporosis (orthoinfo.com). Vitamin D is an important catalyst for absorbing calcium into the bloodstream.

Phosphorus is another vital nutrient to maintain bone health. Nuts, Sesame Seeds, peanut butter, parsley, crab and prawns are all foods high in phosphorus. Don’t feel like you have to eat meat or drink milk to get these essential nutrients.

What Does Cold Weather do to Your Body?

Cold 1936_Pneumonia_prop_strikes_like_a_man_eating_shark

Cold Weather and Lower Temperatures Affect the Human Body

The Human Body is made to deal with the Cold

Cold Temperatures stress the body, but the human body is meant to adapt to colder conditions. You see, low temperatures stress the body; but in a way, it is a very psychological phenomenon. It happens in your mind. The way that you react mentally can have a big effect on how the stress of cold affects you. However, for this article we will discuss primarily the physiological response of the human body to low temperatures.

Over time, the body will adapt to colder conditions. Even brief exposure to low temperatures lead to increased levels of norepinephrine and cortisol, lymphocytosis, decreased lymphoproliferative responses, decreased levels of TH1 cytokines and salivary IgA, and increased lactate levels during exercise. It takes time for the body to de-stress itself in the cold.

Does Exercising Help in the Cold?

Exercising in the cold doesn’t seem to help too much. It can for a short period of time though. Just try not to sweat! Exercising exhausts the bodies energy reserves for immediate heat. Though in general, exercising is a good way to keep the immune system strong. Sweating also causes the body to lose heat quickly.

It seems that previous exposure to cold temperatures is one of the few things that helps the body to adapt. But acute exposure of the skin can have a huge effect on the body’s immune response, so be sure to keep your skin covered in colder temperatures until your body has adapted. They say it takes about 2-3 weeks for your body to adapt to those lower temperatures.

The Cold and the Human Heart’s Health

Cold weather and Cardiovascular Health

People die more often of heart and respiratory diseases in the winter. Vasoconstriction increases blood pressure during the bodies cold-stimulus response. The decrease in cellular plasma also creates a lot more work for your heart.

The Body’s Response to Cold over Time

Exposure to cold causes the sympathetic nervous system to heat the body by constricting blood flow to the extremities and superficial tissue. The body then begins to constrict the flow of the immune system, as well as the nervous system. As the nervous system restricts flow, the extremities lose blood flow until frostbite and more serious, permanent damage occurs.

Who do Mammals Shiver?

Why do you Shiver when it’s Cold Outside?

Over time, the blood pressure increases to cope and the body begins to shiver at a certain point. Once you are shivering heavily, you are at the point where you can get frostbite, or even hurt yourself because the body convulses so strongly. But this can also happen well above frostbite temperatures due to the body’s tolerance level. As people get older, they shiver less, which results in a more rapid drop of temperature upon exposure.

Here’s how Shivering works Neurologically:

Located in the posterior hypothalamus (brain) near the wall of the third ventricle is an area called the primary motor center for shivering. This area is normally inhibited by signals from the heat center in the anterior hypothalamic-preoptic area but is excited by cold signals from the skin and spinal cord. Therefore, this center becomes activated when the body temperature falls even a fraction of a degree below a critical temperature level.

Humans heat themselves Naturally by Burning Fat

Humans also have regulatory neurotransmitters and hormones to help the body burn fat for heat when the body is cold. This is primarily how the newborn and elderly bodies create heat. As we get stronger immune systems, the body shiver response gets stronger, apparently.

Injuries from cold temperatures:

frostbite, hypothermia, heart attacks due to decreased blood flow

No antibiotics, Cough Meds are BS… eat some candy:

Possible explanations may include temperature-induced changes in the respiratory system,[42] decreased immune response,[43] and low humidity causing an increase in viral transmission rates, perhaps due to dry air allowing small viral droplets to disperse farther and stay in the air longer.[44] The apparent seasonality may also be due to social factors, such as people spending more time indoors, near infected people,[42] and specifically children at school.[37][41]

There is some controversy over the role of low body temperature as a risk factor for the common cold; the majority of the evidence suggests that it may result in greater susceptibility to infection.[43] Herd immunity, generated from previous exposure to viruses, plays an important role in limiting viral spread, as seen with younger populations that have greater rates of respiratory infections.[45]

Poor immune function is a risk factor for disease.[45][46] Insufficient sleep and malnutrition have been associated with a greater risk of developing infection following rhinovirus exposure. Due to their effects on immune function.[47][48] Breast feeding decreases the risk of acute otitis media and lower respiratory tract infections among other diseases,[49] and it is recommended that breast feeding be continued when an infant has a cold.[50] In the developed world breast feeding may not be protective against the common cold in and of itself.[51]

The Sciatic Nerve: A River of Energy Suppyling Human Legs

Sciatic Nerve

The Anatomy of the Sciatic Nerve

Also known as the ischiadic nerve or ischiatic nerve, the Sciatic Nerve is the largest nerve in the human body. The Sciatic Nerve runs down the leg behind the bicep femoris and powers the thigh muscles.By KDS4444 - Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=53368293

The nerve begins in the Sacral Plexus Gray Sacral Plexus

 

 

 

 

 

 

as you can see from contrasting the above depictions of the nerve. Notice the outer thigh innervation and middle leg innervation from the upper nerves in the second photo. Contrast that to the inner thigh/back-leg innervation from the lower set of nerves. The sciatic nerve is a combination of the nervous tissue from L4 to S3 and continues down the leg to branch into the Tibial Nerve and the Common Peroneal Nerve at the popliteal fossa.

The Sacral Plexus and the Greater Sciatic Foramen

Here is a fantastic depiction of the sacral plexus and the nerve’s points of joining and separation through the Greater Sciatic Foramen which is covered by the piriformis. Here prentice-hall-sacral-plexusis a great view of the coccyx and sacral plexus which runs down the back of the leg. As the nerve travels, it is hammocked by the piriformis and then the bicep femoris before it branches. You can see a really great example of the support of the bicep femoris below

Posterior-View-of-the-Lower-Limb-Anatomical-Course-of-the-Sciatic-Nerve
Posterior-View-of-the-Lower-Limb

 

You can also see that as the nerve travels, it branches below the bicep femoris and the popliteal fossa which is also known as the knee pit. The biggest bone in the body, the femur supports and protects the sciatic nerve. We could definitely get into more detail about the branching of the nerve, but for now, let’s stick with the major components, we can get more specialized later.

 

Implications for your Yoga Practice

  1. If you haven’t started finding ways the stretch the muscles surrounding and supporting the biggest nerve in your body, its time to start. Finding ways to relax and stretch the piriformis and strengthen the sciatic nerve should be one of the primary goals of your practice. A healthy sciatic nerve will be most helpful in maintaining a pain-free leg!
  2. It is necessary to work into the layers of muscles surrounding the nerve tissue to truly release tension from it. This means that although an adjustment from a chiropractor might help in the short-term, you should be focused on re-aligning the leg muscles in your daily posture to create space for the sciatic nerve.
  3. Your hamstrings can be the primary instigator of your back pain! Quadriceps are filthy culprits as well! Find ways to stretch your legs and your back will often carry less tension as a result. And legs stretches can allow you to stretch the back in deeper ways. There are certain points inside of your hip/sacrum connection where your back and your legs are the same thing!
  4. This is a huge reason why downward dog feels so fantastic. You get to stretch the muscles around your biggest nerves! Downward can be one of the most sustainable yoga poses. It shouldn’t hurt! Just uncomfortable at first.
  5. Just to take the downward dog thing further, this is also why sun salutations are such a universal stretches in yoga and so good for relaxing the nervous system. I think sun salutations might be one of the best exercises you can do for your back.

What are Bones?

Bones are not inanimate rock like structures in the human body; bones are organs that produce red and white blood cells, store minerals, enable mobility, and provide structural support for the body. They are lightweight, strong, and hard, and function within the body in many different processes, including autoimmune function. , There are two types of mineralized osseous tissue, or bone tissue, cortical and cancellous, and gives the bones rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.

Primary Nutrients

Most literature proposes Calcium and Vitamin D as the primary nutrients for healthy bones.

Calcium is important in bone creation and repair. Your muscles, organs, and nerves also need calcium to function properly; nerves use sodium to pump electricity through nerves in the form of action potentials. Calcium helps to keep these actions potentials from excessively firing by working in concert with GABA receptors, most notably in high intensity auditory transduction. (http://phys.org/news/2007-03-calcium-life-death-nerve-cells.html). Leafy greens, fish, and some fruits are great sources of calcium.

Vitamin D is a group of secosteroids responsible for intestinal absorption of primary nutrients such as calcium, iron, and zinc. Vitamin D is synthesized in the skin is the primary way that the body produces the nutrient; though it acts as a hormone because the nutrient travels to become active in the liver and kidneys. Vitamin D has a significant role in calcium homeostasis (balancing) and production in the kidneys and liver. It also affects neuromuscular and immune function.

Protein, magnesium, Vitamin K, and phosphorus are also suggested as beneficial nutrients for bone health.

Bone Structure

Bone tissue, bone marrow, blood vessels, epithelium, and nerves make up the different types of bone cells. Tissue includes Osteoblasts and osteocytes, which are involved in the creation and mineralization of bone; osteoclasts reabsorb bone tissue. The mineralized matrix of bone tissue has an organic component of mainly collagen called ossein and an inorganic component of bone mineral made up of various salts. Bone tissue refers bone_layer_imagespecifically to the bone mineral matrix that forms the rigid sections of the organ. There are two types of bones: cortical and cancellous. Cortical bone tissue create hard exteriors for protection while cancellous bone is more spongy and allows for the metabolic processes on the interior of the organ; the two are biologically identical, but the expression of their microstructures are specialized.

Bone marrow is flexible tissue and reproduces red and white blood cells as well as lymphocytes that support the immune system. Cores of marrow in the heads of long bones create about 500 billion red blood cells per day in hematopoiesis. 4% of human physiology is bone marrow; so about 5 pounds if you weight ~125. The body creates two types of marrow: red, the only type in the body at birth; and yellow, which increases in proportion during the aging process. Transplants can cure extreme diseases and is one of the primary reasons why stem cells can be so beneficial. The body stores marrow in the femur, hips, vertebrae, and ribs.

Osteo Factshttp://training.seer.cancer.gov/index.html

At birth, there over 270 bones in the body, which during the aging process turn into 206 by fusing together (joining). The biggest is the femur
(thigh) and the smallest is the stapes in the inner ear.  The hard cortical tissue (outer layer) comprises 80% of mass and networks of trabecular marrow comprise the rest. Bones are mineral reserves for the body and marrow stores fat. They are metabolically very active and work in tandem with the digestive system, immune system, and endocrine system in balancing nutrients, defending against disease, and releasing hormones, respectively. 22 bones fuse together after birth to form the skull. 26 aligned, specialized bones called vertebrae make up the spine, protect the spinal cord, and form the primary support structure for the body.

 

Aging and Osteoporosis

The problems arising from bones occur in osteoporosis, fractures, arthritis, tumors, and infections can affect the organic tissue. Fractures are breaks in tissue, from repetitive force or trauma. Aging causes osteoporosis; the body stops producing the necessary amount of building material for the body and literally means “holey bone” (porosis meaning hole). Tumors and malignancy’s can occur in various forms in bone tissue as well. This makes it much easier for the bones to fracture.

Cancer

Cancer can also occur in tissues structures and is a common site for it to metastisise to. Several primary cancers occur within the bones and some even within the marrow, such as Leukemia and multiple myeloma. The tissue distorted by cancer is normally more prone to fracture and weakness, which becomes particularly painful when it occurs in the spine.

Evil and the Evolution of Morality

The Idea of Evil Giovanni Domenico Ferretti, Cain and Abel, 1740

Evil and Humanity

Evil and morality are thought structures for defining good and bad actions. Definitions of evil vary according to the culture, time, and context of the people who are defining it. An absolute definition is illusive. Many describe it as a supernatural force in our world. Some say that it is led by satan, the opposite of god. In Catholicism, this would refer to lucifer’s betrayal of god and descent into hell. Evil ascribes a certain kind of ignorance, selfishness, neglect, ignorance, and amorality.

Logical Beliefs about how evil exists

There are four different logical possibilities regarding evil, one of which you will fall into. Moral relativism is the belief that morality is shared amongst a group of people, but relative to individuals. That means that each group of people believes themselves to be ethically or morally superior to the others; most philosophers question the idea of an objective morality. It holds that morality is flexible to the cultures that employ it. Most critics of this view claim that this creates a logical conundrum, whereby judgements of morality cannot be applied.

The second possible belief is moral absolutism, where you believe that particular actions are inherently right or wrong and that certain restrictions on behavior shouldn’t be violated. Immanuel Kant’s views on duty and rights can be placed into this category. For instance, if you believe that violence should never be used even in self-defense, than you are morally absolutist about violence being wrong.

Moral universalism, or moral objectivism is the meta-ethical position that some systems of ethics apply themselves universally to a like group of individuals. For instance, all humans should not steal. This is directly opposed to moral relativism or nihilism because it creates a common standard by which all beings should act. This is an Abrahamic belief, meaning it is shared amongst the biggest religions in the world: Christianity, Islam, and also Judaism. This is the view that the United Nations adopted in 1948 after WWII, in Paris.

Amorality is the disregard for morality. This is different from immoral, which refers to the subject views of the agent/doer. Any being that is not able to act with judgement is categorically amoral. Friedrich Nietzsche rejected morality by saying that he had to for non-moral reasons. Moral Nihilism is an offshoot of this, whereby someone would consider killing someone as neither moral or immoral, which is pretty much the direct opposite of moral objectivism.

Now, you understand probably where you fall, but it is important to remember that animals, most particularly domesticated animals with exposure to human values and behaviors can develop a sense of morality as well; just think about your dog or cat. You can also be certain that this exists within animal communities for the sake of well-being for the entire community, but evolving as a sort of natural phenomenon (think of a flock of bird, or school of fish that work together by instinct).

Morality as an Evolution for Social Species

So let’s explore how morality has evolved to become what it is today, certainly led by the virtuous altruism and nihilistic amoral exemplars from the human race.

Carl Jung talked a lot about evil as a shadow-side inherent in each human, but believed to be a separate force from themselves by each individual. People project their own shadows onto others; their insecurities, fears, stresses, etc. He believed the story of Jesus to be an account of God facing his own shadow side.

Morality is certainly an evolutionary lens of humanity; we invented its examination over the course of our evolution. Morality is system of ideas about right and wrong, originating with mythology and evolving most drastically with religion. Most scientists argue that human moral behaviors can be traced through animal behaviors and instincts. Many scientists argue that there is an intrinsic science behind morality, though social scientists general consider morality to be a construct.

Evidence suggests that all life on Earth has a single common ancestor, a small single-celled organism that lived 3.8-3.5 billion years ago. But as we learn more and more about horizontal gene transference, which is the primary mechanism of gene transfer within micro-organisms, we are starting to understand that this single common ancestry might have evolved differently than we currently hypothesize.

This has led to mammals and social societies within animal species with specific hierarchies where each individual knows their place. Social order is maintained by rules of expected behavior and consequences for actions. Higher functioning primates like our closest relatives, chimpanzees and bonobos often reciprocate social behaviors and remembers favors, favorites, preferences, empathy, attachment, bonding, and altruism. Vampire bats reciprocate by sharing blood regurgitation with their bat friends, or those in dire need of feeding. Certain monkeys and dogs refuse to act unless rewarded properly and fairly for their actions.

Chimpanzees lives in groups of about 50, forming complex societies with distinct and unique hierarchies. Paleolithic hominids (2.6 millions years ago to 10,000 years ago) lived in groups of a few hundred individuals. Malcolm Gladwell mentions that humans have a limit of about 50 close friends and 300 in their extended circle, which is of course aided by advancements in technology. As community size increased, morality evolved as a means of control, cohesion, and solidarity. As the number of individuals within communities increased, so did the complexity of these hierarchies and moral systems until things like religions, cults, and more complex societal functions began to emerge.

How are Human Morals Different?

Humans societies have two major differences that separate our societies from primate and higher functioning animal societies. We enforce our moral codes more strictly with punishments, rewards, and reputation building. Humans also have a degree of abstract reasoning and objective judgement that is not present in the animal kingdom.

Morality has evolved so far that it has created a sense of human altruism that is even greater than the urge to pass on genes in many instances. This theory of collective social mind that humans can infer or transfer to each other with high levels of intelligence is an evolution that is displayed in primates, but never as heavily or significantly as in humans. Neither is the altruism that humans display towards the collective.

Psychologists believe that religion may have evolved from morality and used supernatural principles and entities to keep the group cohesive and allow the collective to adapt to the ever evolving needs of the collective with enhanced chances for cohesive survival.

There are two primary expressions and emotions involved with morality: the first is disgust; the second is shame. Both of these contribute to a social punishment system that is very active in the world around us today, especially on the internet.

Religion, Morality, and Evil

Finally, here is a list for each religion, categorizing how it’s doctrine thinks about evil:

  • Hinduism – Dharma divides right from wrong with strict systems of morality based on actions.
  • Christianity – any thought or action against the will of God is immoral.
  • Judasim – evil comes into existence through the actions; humans are responsible for choices.
  • Islam – there is no concept of absolute evil. Evil is lack of good, or disrespect of Allah.
  • Buddism – Desire is the root of all evil, but more focused on suffering and ignorance.
  • Sikkhism – evil evolves depending on one’s location along the path to liberation.

Conclusion

Remember that I am doing my best to be impartial here; if you feel like something is missing please add a comment! Evil is certainly something that has evolved with humanity and continues to evolve today, though I did my best to steer clear of any news on the subject.

This wraps up my discussion on the idea of evil, morality, and the evolution of what is right and wrong. I’m hoping to write my next article about Aristotle his concept of “the good”, if you have anything you want me to mention or discuss, let me know!

Yoga’s Primary Benefits: Control of the Autonomic Nervous System

Yoga's Primary Benefits_autonomic_nervous_sytstem

Yoga’s Primary Benefits

Honestly, yoga’s primary benefits are still unknown. Our science isn’t good enough yet. Not really. Science is just starting to catch up to the power of some of the world’s most ancient healing traditions and are learning their meaning in a whole new light. Yoga’s primary benefit  is certainly related to the functioning of the central and peripheral nervous systems, but how is something that has yet to be explained. The Ujjayi breathing technique, or breathing slowly through the nose is almost certainly related to yoga’s primary benefits; how is something that we have yet to learn. The Western world is slowly learning that the Eastern traditions, medicines, healing techniques, and ritualistic traditions are grounded in some serious observational science, even if it isn’t quantifiable and measurable by current methodologies and technologies. Even if the causes aren’t completely explained. This is happening in Acupuncture, herbology, nutrition, Ayurveda, and even Yoga is one particular field where we are learning a lot about how beneficial something as simple as breath control can be. The human body is more complex than we can currently understand; we are continually learning more about the human ecosystem that is what we define as our body.

Yoga is one particular tradition that reaches very far back in civilization, but our scientific knowledge about how yoga can help the body to heal is fairly rudimentary. We know from clinical studies that yoga helps with sleep duration and quality of sleep, we also know that it helps with anxiety, depression, and stress. But yoga in our modern society mostly means exercise, something that is vastly under-rated in American culture and in our society; 66% of Americans are overweight.

Yoga almost certainly has benefits to the endocrine system, the respiratory system, the circulatory system, the heart, and the digestive system, but many of these benefits have yet to be measured. Even our understanding of the functioning of the respiratory system is still somewhat archaic, especially in terms of the lungs interacting with the heart, especially in the paradigm of disease. We have a lot to learn, but another, even more powerful benefit that we are learning about is the control one gains over the nervous system.

Yoga and the Nervous System

The nervous system is the central source of energy for your body; the electricity in your body is the fundamental source of energy for your body and therefore your consciousness to exist. The electricity that runs down your spine and into your peripheral nervous system, or the legs, torso, arms, organs, and every other part of your body is a continually firing process that continues from before birth and ends with our final breath. This is what allows us to be alive and is the fuel for our internal fire, passion, love, and existence.

This nervous system that we have evolved into over billions of years is extremely adaptive; different aspects of it have partitioned and specialized; we have a parasympathetic part of the autonomic nervous system and a sympathetic part; a conscious part of the nervous system and an unconscious part of the nervous system.

Yoga and Stress Regulation

The parasympathetic autonomic system is largely outside of conscious control and regulates most of the “background activities” of the body, such as digestion, sexual activity and arousal, urination, etc. The sympathetic nervous system allows us to control our fight or flight response or panic responses. Yoga allows us to tap into both of these systems Yoga's Primary Benefit LiveScience_Nervous_Systemand influence their activities and awareness breeds control, making awareness of the proprioception of the nervous system a primary benefit as well. That’s why balancing in yoga is such an important part of the practice.

One of yoga’s greatest benefits that is also a byproduct of meditation is alleviation of tension from the muscles, cortisol from the bloodstream (stress hormone), and slowing down of the heart and therefore circulatory system. Control over the nervous system helps us to do this because it allows everything else to slow down as a result of slowing the mind, and allowing the body to reach equilibrium and decompress. This can help us to fully relax in preparation for strenuous activity and the two can balance each other out really nicely because of yoga’s benefit to slowing the nervous systems.

I’ve done yoga in airports, on airplane bathrooms, in buses, in random hotel rooms, in airplanes, in cars, in RV’s, while camping, after long days of strenuous activity, etc and I will always use it to keep my circulatory system “feeling good” while traveling. The benefits of yoga for the body are undeniable and we are just starting to learn about the real consequences of this powerful, healthy, spiritual, and enlightening practice.

Sustainable Life: 5 Actions you can take NOW

Sustainable Life

Sustainable Life for Humans

Humans are on a crash course with our destiny. If we don’t find a way to live sustainable life, our species could become extinct. Over the next five-hundred, the extinction of our species will looms above us, as it has in the past. Will we fall into the oblivion of our over-consumption and completely destroy our eco-system? Or can humanity persevere into sustainable life and even become something greater than we have ever imagined? Could humanity bring life to new worlds and expand into a universe of global consciousness? Anything seems possible with human ingenuity.

There is no doubt that there are major issues that threaten the survival of the human species, namely our consumption patterns. There are five major actions you can take today for humanity’s future.

  1. Stop eating meat; move to a vegetarian or largely vegan diet. Cavemen were opportunistic carnivores; we will discuss these implications for your diet and for planet Earth. This is something you will almost never hear about, but has the biggest implications for our planet.
  2. Make your own things. If you need to buy something, understand the product life-cycle before buying (especially cars!). This is called “ethical consumerism“. We’ll come back to this.
  3. Try to drive less on a daily basis, but enjoy traveling long distances a few times a year. Your oil consumption matters, but there are other things that you consume that matter more. (hint: go back to #1)
  4. Stay away from authority. (police, judges, courts, politicians, bosses, anyone with a gun, or that thinks they can tell you to do something; teachers often also fall under this category when you a young). The idea is to limit your encounters with these types of people as much as possible to avoid conflict and destructive behavior.
  5. Enjoy a nice meditation, stretch, or even some yoga. Spend more time away from TV, screens, and stimulation/electronic radiation. Walk, run, hike, be outside, find outdoor activities. You’ll look better for it. Remember to enjoy the present moment whenever you can. It’s all that we really have.

These are just a few principles to help you live a simpler, more economized, sustainable, and efficient lifestyle.

Now, let’s talk about sustainability.

You want your life to be sustainable. You want your children to enjoy what you have enjoyed in your life. And through your life, you’ve realized what is important and it is surely not things! If so, you are living excessively! When there is excess, there is stagnation, we see it in all kinds of royal families throughout history and now in the wealthy corporation owner families like Wal-Mart. They always get slaughtered and killed in revolutions and replaced with leaner governments with more representation from citizens. This might happen soon in this county, but there are actions you can take to stop your over-consumption and to be a lean consumer.

The truth is that no one really values sustainability. Everyone wants more because they think that it will make them happier. Corporations want you to believe this! But this type of consumption couldn’t be further from the truth.

You do not value things. You can lie to yourself all you want, but if there is a bigger TV out there, you are going to want it! This means that anytime you buy a TV, this will inevitably lead to dissatisfaction, whether it is because a larger/more inexpensive TV is being produced, or the TV that you have breaks. Understand the tricks that your mind plays on you. You want things that will last, especially when you invest lots of money into these things.

The First Steps

Your meat consumption will have the largest effect on your world. Consider this: animals are living breathing beings just like you and they need to be taken care of. This includes water, food, warmth, medicine, and social interaction. Right now, we can’t even give the animals social interaction because they are too numerous. We over-medicate them because they are too numerous. The whole system is completely unmanageable because everyone wants to eat meat.

A human diet optimally contains mostly vegetables, fruits, legumes, and nuts for health. Most people don’t need meat and can subsist on a completely vegan diet. However, some people do need meat in their diets. These people can absolutely live on chicken and bug proteins (just like our ancestors). Human beings are absolutely not meant to eat red meat in large quantities. We simply do not have the stomach acid to break it down, which results in acid reflux, compacted digestive systems(think about old men with huge “beer bellies”; meat is the real culprit here), and slowed metabolism and digestion because of nutrients that are too densely packed for a human stomach to efficiently digest. Advancements in science are also helping to improve this, making fake meat tastier and closer in texture to real meat, but really our ancestors had very limited access to meat. You only need it occasionally.

Be Aware of your Water Consumption

We Americans use the most water of anyone in the world by at least 2x. Japan is the only country very close to us. How do we use so much water? Beef. Cows drink enormous amounts of water and they are an extremely inefficient converter of energy. Cows are the biggest reason why we Americans consume so much water.

We also take long showers, wash our cars, water our lawns too much and waste water on completely unproductive plants and animals. The key here is unproductive land. We need to use our land to cultivate healthy and nutritious food for ourselves and stop relying so heavily on mass farmers so they can be reasonable about their crops. We undervalue food in this country. I’m not talking about fancy restaurants; I’m talking about produce aisles at the grocery store.

Vegetables require far fewer nutrients, water, care, and money than cows do. That’s why you’ll never hear about this in the news, or on T.V. People have literally been killed over it. There are billions of dollars in beef and the beef companies want to keep it that way.

Showering for shorter times helps. Doing laundry only when clothes are really dirty also helps. Not watering your lawn is also a huge contribution. But rest assured, beef is the #1 culprit for water loss in this country.

Stop Being a Mindless Consumer

This is really all that you have to do. This falls under what we talked about earlier in the second point about ethical consumerism. Understand that all of the products in target and Wal-mart are made in China, basically in labor camps forced by the Chinese Communist government. They would do the same to Americans if they could and they do get away with quite a bit already! That is what you are supporting when you want to save money at those stores. All of fast-food comes from factory farms. They are the worst ones! I’m sure that McDonald’s cow’s aren’t loving anything that is being done to them. Neither are the pigs or chickens from all of the other fast-food chains. Deli meats are no better, don’t try to kid yourself. You wanna look lean, sexy, and be healthy? Stop eating meat altogether. Give it a try, don’t try to kid yourself that you need it after a week. You could survive without food for something close to 3 weeks. I’ve gone 5 days myself and didn’t lose too much weight, but I was also very thin and already living in India.

If you want high-quality, long-lasting products, then we have to invest in the art and craftsmanship of the people around us. The paintings that no one knows about have the highest mark-up anyways. Products with character and durability are getting harder and harder to find and its a shame. It’s an art to create beautiful crafts and we need to remember to value that and support the people who make it.

So it’s simple. Sustainable life is all about your decisions. Your existential power in this universe. Consider where your money goes, how it is funneled into the economy. Be serious about understanding your own patterns of consumption, and then you can run on next to nothing, or sustain yourself completely.

You can do it!

The increased knowledge of gut bacteria is a an excellent example of a paradigm shift in the health community. The scientific community has obtained an incredible amount of knowledge from this new field of microbiology. The gut flora is sometimes considered an organ because of its importance, this community of micro-organisms is evidenced to protect its host (that’s us) from pathogens and allow us to extract nutrients from our diet.

Your colon contains over 100 trillion micro-organisms most of which are bacteria. It also has the most complex and intricate interactions of the human micro-biome. The flora in the stomach and upper intestine are not as diverse or populous. This “gut” ecosystem is complex with over 400 species (identified genomes) but not quite as numerous as the 1,000 different genomes of skin micro-organisms. This is probably because of the skin’s increased interaction with the environment.

Bacteria populations within the gastrointestinal tract differ greatly depending on the host: geographical location, diet, genetics, even the behaviors of different species are vastly different based on the history of the host. Not surprisingly, diet is probably the largest factor in the populations of bacteria in the gut.

These bacteria have lots of different functions: synthesizing vitamin B and K, nutrient extraction, metabolizing bile acids, sterols, and xenobiotics, defense against pathogens, cell growth stimulation, and response to disease. They are often referred to as the forgotten organ because of the immense role they play in digestion and little attention they have received until more recently.

Gut flora evolve during the course of an individual’s life. These microbiota are non-existent until birth, and mature at the age of 3. Micro-biota are normally associated with nutrient intake, and concentration of communities are indicative of the type of diet of the host. This ecosystem, or microbiome in the gut is essentially your metabolism and what allows your body to breakdown and re-intake nutrients from your food sources. They believe this may be a reason why breastfeeding is important for infants; the nutrients help to form the initial microbiome of the child.

Without these bacterial cells, our bodies wouldn’t be able to breakdown certain nutrients. They also help the gut to maintain efficiency, especially in the colon. The colon has a lower pH level than the rest of the body, preventing harmful bacteria from proliferating and possibly even enhancing the excretion of carcinogens (cancer causing agents).

Gut bacteria have a primary role in nutrient absorption, especially electrolytes, and help the body to control its fat levels. They also help to fight allergens including over-action of the immune system. Some bacteria can even stop inflammation during the digestive process. Some genus’ of bacteria aid cancer growth, while some fight it. There is increasing evidence to suggest that obesity might be caused by bacteria populations and that the two could be intricately related.

The populations of micro-organisms in your gut is not to be under-estimated, we will be learning more about the implications of gut ecology on diet, health, and especially in obesity regulation over the next few decades. This is one of humanity’s primary links to the environment and is essential for optimal immune function. As we learn more about allergies, we will also be learning more about the ecological properties of our own bodies.

The last article in the series should be out soon, stay tuned for the implications this research has on the future of modern medicine. Questions or corrections are always welcome!

this human really needs to floss

Your mouth harbors a diverse, abundant, and extremely complex community of microscopic organisms. These bacteria form biofilms on the soft and hard tissues of your mouth, tongue, cheeks, tonsils and upper throat; this adhesion allows them to stick on the surface. Essentially, these bacteria form a sticky or slimy film that builds-up over time. These biofilms are known as plaque and their build-up is what causes dental diseases, such as periodontal disease (which research suggests is always preceded by gingivitis) and dental caries (cavities) as well as other diseases if they are able to enter the bloodstream.

Plaque (oral bacteria) build-up in the mouth is normal; its control is what prevents tooth decay and gum disease. These bacteria have evolved mechanisms to evade and modify the host; the host in turn has a defense system that monitors bacterial colonization and prevents invasion. This equilibrium between the host and bacteria is dynamic and varies greatly from person to person.

When we are born, our mouths do not contain any bacteria yet; during the course of development bacteria accumulate to allow for the dynamic equilibrium that I previously mentioned. Some major landmarks are the growth of teeth, and full maturation at about the time of puberty. Some names of the bacteria are streptococci, lactobacilli (common in probiotic supplements), staphylococci, corynebacteria and some other anaerobic bacteria (non-oxygen consuming); streptococcus salivarius (think saliva) is very interesting because it colonizes the mouth and upper respiratory tract just after birth and is an opportunistic pathogen, meaning it rarely finds its way into the bloodstream to cause harm (usually a decrease in white blood cells) and is mostly beneficial to digestion.

You can probably see why disrupting the bacterial growth in your mouth is a daily activity; plaque build-up can cause unhealthy amounts of bacteria in the mouth, especially with large amounts of sugar consumption. Flossing should be a daily activity as well because it performs the same functions as brushing in that it reaches the places that your toothbrush doesn’t in between the teeth and along the gum-line. However, I think that brushing three times a day is probably somewhat of a myth promoted by the dental industries; once a day is probably all you need, unless you are eating food with high bacterial content or sugar content regularly, or food with high acidity (which is probably the case if you are vegan, vegetarian, or just eat lots of fruit).

The WHO (World Health Organization) says that nearly all adults have dental carries during their life. It’s estimated that currently 36% of the population has carries and that number is steadily increasing as the world becomes more developed because of simple sugar consumption. Remember that bacteria love sugar!

Interestingly, kissing with full tongue contact is evidenced to provide exposure to the oral micro-organisms of  the other and could be an indicator for the hosts about the bacterial health of their partner. This might indicate mating compatibility, amongst other things. Some of the bacteria that are shared on the tongue’s surface have long-term colonization effects, meaning that kissing might lead to increased diversity in tongue bacteria. Cool, right? So kissing might be some kind of a test for bacterial compatibility in your potential mate during the courting process.

This article is probably the shortest in the ecosystem of the human body series. I hope you are enjoying it! Part 4 is all about gut bacteria, so check back soon to learn all about gut health.
